Error trying to build, after getting the latest cygwin changes

[Bob Cassels <bcassels at abinitio dot com>]

I've been building Cygwin from the sources successfully for a week or so 
now.  This morning I updated from CVS, and built.  But using the resulting 
new-cygwin1.dll (copied to /bin and renamed to cygwin1.dll,of course) no 
longer lets me build.  I get this error:

      ar: cygdll.a: File format not recognized


If I restore the original cygwin1.dll, I do not get this error, and I can 
successfully build.  I tried this with the sources directly form CVS, 
without any of my changes, and got the same behavior.

Thanks,

Bob Cassels



Below is more of the 'make' log, so you can get a little more context.  (I 
'touch'ed a file to force make to do something.  This is still the sources 
without my changes.)
